Lifting device capable of positioning corner

Abstract

An elevating device can position a corner. One end of a handle of the elevating device is fixedly connected with one end of a push rod, another end of which is provided with a U-shaped slot. The push rod and one end of a guide rod are linked inside the U-shaped slot by the pattern of hinge joint. A soleplate is provided with a knuckle bearing, and the guide rod is put through the soleplate and is synchronously articulated at the knuckle bearing. A tension spring is fixed at the middle part of the push rod, and another end of the tension spring is put through the soleplate and is connected with the terminal end of a guide slot, which is fixed at the bottom of the soleplate. The terminal end of the guide slot is also connected with a pressure spring, another end of which is connected with the guide rod, which is put through the guide slot. An outside cylinder is provided with a blocking plate and a sleeve of the blocking plate. The blocking plate and the sleeve of the blocking plate are arranged as interference fit. The sleeve of the blocking plate also meshes the soleplate, and the sleeve of the blocking plate and the soleplate are all blocked tightly with interference. The bottom of a pedestal cylinder is fixed at the pedestal. The inside of the blocking plate is provided with a plurality of blocking slots, which match with the shape of the guide rod. The elevating mechanism can ensure the function of elevating and at the same time can realize the function of rotary positioning, and the use performance of the elevating mechanism is improved, and the structure is simple, and the operation and use is flexible and convenient.

Description

technical field [0001] The invention relates to a lifting mechanism, in particular to a lifting device capable of positioning a corner. Background technique [0002] Existing rotatable lifting mechanism usually adopts pneumatic lifting device. For example, the patent No. 02250660.8 is the reinforced pneumatic lifting rod. When the lifting device needs to be rotated at a certain angle, it cannot be automatically positioned at the required rotating position, but requires the user to use additional force or devices to clamp and fix it. , very inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a lifting device capable of locating corners. The lifting mechanism can realize the function of rotating and positioning while ensuring the lifting function, and improve the performance of the lifting mechanism. It has a simple structure and is flexible and convenient to operate. [0004] The present invention solves its technical ...
